TYPE-WRITING MACHINE.-

SPECIFICATION. forming part of Letters Patent No. 442,697, dated December 16, 1890.

Application filed Tuly 3, 1889. Serial No. 316,398. (No model.)

To @ZZ whom, it may concern.:

Beit known that I, JOHN NEWTON WIL- LIAMs, a citizen of the United States, residing at Brooklyn, county of Kings, State of New York, have invented certain new and useful improvements in Type-riting Machines, of which the following is a specification.

My invention relates to a type-writing ma'- chine of the style in which the writing or impression is produced on top of the platen, constantly exposed to the inspection of the operator, and the forms of type-carrier and paper-carriage movements, which are the principal features of my invention, are especially useful in such machines, because they lend themselves to the prime object-that of leaving the platen open and unobscured.

My invention consists in certain improvements, first, on the type-carrier mechanism, and,second, on ti: e paper supporting and shifting devices.

. Referring to the accompanying` drawings, which form a part of this specification,Figure 1 is a central vertical section of a typical form of my machine, omitting all parts except the t ype-carriers and those parts necessary to their operation. Fig. 2 is a plan view of the entire machine in its improved form. Fig. 3 is a vertical central section of the same. Fig. 4 is a vertical transverse sectional viewin the plane indicated by the lines 4 4, Figs. 2 and 3. Fig. 5 is an end view of the platen and associated parts. Fig. G is a perspective view of certain of the same parts disassociated. Fig. 7 is an axial sectional view of the linefeed ratchet-Wheel. Fig. S is a perspective view of the paper-carriage-carrying frame and associated parts, the paper-carriage and steplay-step feed-rack being omitted. Fig. 9 is a sectional detail view of a single type-bar and associated mechanism with a specific view, showing the action of the counterbalancespring. Fig. 10 is a perspective view of the `feed-rack and associated parts. Fig. 1l is a sectional view of the front pa per-holdin g cage and pressure-bar and platen. Fig. l2 is a detail view of the platen and rear paper-holding devices.

For the type-carrier mechanism I employ in the typical form of machine (shown in Fig. l) the parallel-ruler movement, and in the improved and preferred form (shown in Figs. 2 and 3) a modified form ot' that movement.

Referring to Fig. l, it will be seen that the type 1 (preferably three on the under side of each block 2) are carrried on the ends of bars 3, which normally rest in a horizontal plane on the fixed frame 4 ofthe machine. The details of the frame will be described farther on. Each type bar or carrier 3 is pivoted or vhung upon two links orarms 5 6, which at '7 8 are respectively hinged to the xedframe.

An arm 9, as shown at the left of Fig. 1, or a toothed segment 10, as shown at the right of said iigure, is formed rigid with link 6 and is connected to the finger-keys 11.

In operating the machine depressionof the key will cause the arm 9 or segment lO t-o be turned and will lift the type-bar, keeping it horizontal all the while, and carry it .from its position of rest on the frame up and then down to a position where the type will rest on the platen 12. A reverse movement will bring it back to rest on the frame. The positionat rest is shown on the right of Fig. `1, the projected position on the left of said figure in full lines, and an intermediate position, also, on the left in dotted lines. The typeblock will describe approximately a half-circle, as shown by the dotted curve. It will be seen that such a movement will lift the type from a position sufficiently remote from the platen to leave the latter clearly in view,pro ject it out toward the platen as it rises, and then bring it down onto the platen with a substantially vertical stroke, enabling the blow t-o be given with sufiicient force and without any such sidewise or endwise movement as mightblur the impression. The movement illustrated in Fig. l is susceptible of some important practical improvements with the object of lessening the movement of the key-levers and increasing the directness of the downward stroke on the platen. Such improvements are embodied in the machine illustrated in the remaining figures, which I will now describe.

The type-carriers 8 (see Fig. 3) have preferably a downward bend at 13, so as to bring the types `somewhat below the top of the frame of the machine when the types are in the projected position. This enables the projected type-bar to lie diagonally across and above the type-blocks, remaining in normal position on the ink-pad.

The link G--the one farther from the typeis made longer than link 5. The object of this is readily seen. It is unnecessary that the outer end of bar 3 have any other than a longitudinal or front and rear movement; but in order to clear the frame and paper and impart the proper blow the inner or type end should have as well an upward and downward movement as nearly vertical as possible. By lengthening the link G relatively to the link 5 I am enabled to give as great a longitudinal blow to the type-carrier with a less movement of the link (i around its pivot, and consequently a less depression of key, and'V at the saine time the directness-andforce of thed'ownward blow of the type is increased. 'Fh-is is well shown by the dotted curves at the leftof Fig. 3, the are described by link G bei-ng quite flat, the arc ot` link 5 much more arcuate, (near-lya half-circle,)v and the arc of the type still more arcuate-about one-half of an ellipse.

There are two groups of type-blocks, one in front and one in rear ofthe platen, each resting normally'on ahorizontal ink-pad 14, placed in a Hat.- curved pan 15, supported on the frame by pivots 15. Thetype-blocks of each group are arranged parallel and close together and their several type-bars radiate from a common center over the platen. The type-bars have a varying horizontal bend at 19, (see Fig.. 2,) increasing from the center outward to bring alll to the proper radial position. Seats 16 in concentric cross-bars 17 18 of the frame hold and stead-y the type-bars or carriers in both normal an'd projected positions. To maintain align ment in striking the platen, it is preferred that the seats 16 on the inner cross-'bar 17 be of such depth as to arrest the type-bar just as or before the type touches the platen, so that the arch formed by link 5, type-bar 3, and type-block 2, (see Fig. 1,) being supported at its center, will not flatten under the stress'oi` the blow. The innerlinks 5 are preferably bent somewhat, as shown, so that they will clear the ink-pad and adjoining type-blocks when the type-carriers are in projected position.

The horizontally-arranged ink-pad, against the top of which the type returns after each impression, is a feature which is of consider able practical importance and one'which is rendered possible by the peculiar type-carrier movement employed. The ink-pan, be ing closed at bottom, is adapted to receive a supply of ink which will be long retained. The type are always inked in readiness for the impression and are so moved to and from the pad that the latter offers no frictional resistance. The type print directly from then' face, so insuring aclear-cut clean impression. The pivoting of the ink-pad enables the type to always find a seat upon it. Ity may be readily removed and renewed.

v In the present case the supports for the pivots 7 8 of the links 5 (3 consist of bent bars 20, fixed under one of the curved bars 18. Rigid with the links G are arms 21, which are attached to the upper ends of tension-springs 22. The lower ends of the springs are, as shown at the left of Fig. 8, fixed to the rigid bar 23 of the frame, or, as shown at the right of the saine figure, to the extreme .rear ends of the key-levers 24. It will be seen that the first method of attachment of the springs is appropriate for those in the front of the inachine and the second for those in the rear of the machine. Those key-levers which run to the rear of the machine are connected to the rear links 6 by push-rods 25,hinged to theV Apart way to the rear of the machine andv are hinged at 26` to floating levers 27. Normally the levers 27 bear upward loosely at their front ends against. the under side of basepiece 28 of the frame, and at their rear ends are hung on' pull-rods 29, hinged to arms 9ct links 6.

The left of Fig. 1 shows the parts in the position they assu me when a key is depressed.

The arms 9 are so arranged as to be' ap-A proximately horizontal when at rest, so as to start with little resistance. The key-levers pass through slots in an inclined face-plate l, which, with the bent shields 32, hides the mechanism of the machine from view. (This matter is the subject of claim, and is more fully illustrated in my application filed November 20, 1890, Serial No. 372,119.) All of the key-levers'have lugs 33 proj ecting up through slots in a cross-bar or girder 34, and rods 30, passing through the upper ends of lugs 33, servev as pivots for the latter and for their respective key-levers".

The practical necessity which exists of arranging the keys in a bank of several rows the different lengths of the key-levers necessary for actuating front and rear type-carriers and the dierent methods employed for connecting the key-levers and the type-carriers at front and rear of the .machine render it desirable that some latitude beallowed in the location of the key-lever pivots, so that leverage exerted and the touch of the keys shall be substantially equal. With this end in view the bar or girder is made wide enough `from front to rear to receive two or more series of bearings for the lugs 33, and the latter are hung therein at a forward or rear point governed bythe above-stated considerations.

Depression of any ot' the keys connected with the front grou p of the type-carriers will force down the corresponding floatinglever 27, the latter being allowed at its forward end under the frame 28 the slight freedom t0 slide which may be necessary. This draws down rod 29 and-projects the proper type-bar in the manner already described. The spring 22 resists this action, and on the release of IOO IIO

the key returns all parts to normal positions.

The same spring at all times maintains the parts under tension, its strain being so exerted as to prevent any backlash or loose movement of the parts. Thus depression of the key is felt instantaneously and without loose movement of the type. The operation of one of the rear type-carriers is similar, the parts being kept under tension by the spring 22, which is elongated by the rising of the outer end of arm 2l.

The links or arms 5 have projecting beyond their pivots shorts arms 36, Fig. 3, from which hang links 37, hinged at their lower ends to free ends of wire counter-actingsprings 38, whose other ends are fastened to the frame. The springs 3S are so bent as to exert a constant downward pull on the arms 3G; but it will be observed that this pull only becomes effective when the arms 36 are about in horizontal position at one or 'the other end of their movement-that is to say, when their stress becomes important in overcoming the gravity and toggle action of the links. this means the softness of the touch is found to be very lnaterially improved.

The paper-carriage of my improved typewriter moves on a single track. l2 is a wooden or metal rubber-covered roller of cylindrical `or approximately cylindrical shape. lts trunnions 39 are mounted in the vertical arms 40 0f a supporting and guide bar 4l.

42 is the track-rail, arranged immediately under the bar 4l. The adjacent faces of bar 4l and rail 42 have V-shaped or equivalent grooves to receive anti-friction balls 43, preferably two in number, and so separated by pins 44 that both ends of the platen will be sure of support at all times. The shape of the grooves is such that the gravity of the carriage will bring itralways to central position, and yet it will rest on each. ball at but two points and so move with but little friction. The-track or rail 42 is of girder form, ofsuch depth as to give a bearing for the steadyingrollers 45 4G, separated from the balls 43. Strain and friction-are thus avoided. The roller 45 runs in a groove in the bottom of rail 42 and is carried by the same pin 47 as the roller 46, which is so held up to the side of the rail by spring 4S as to yield slightly to sidewise movement. The pin 47 is carried by the lower end of an arm 49, pendentfrom and rigid with the bar4l. It willbe seen that the weight of the carriage is all upon the balls 43, as well as the principal guiding act-ion, the rollers 45 46 serving simply to steady the movement and prevent accidental displacement of the carriage from its track.

As, in order to lessen the number of keys, two or preferably three types are carried by each type-block, it is necessary to provide for the relative shifting of type-blocks and platen, to bring one or other of the types on each block into play. This may be done by shifting either the type-carriers or the platen.

The platen.

In another application I shall describe means for shifting the type-carriers. In the present application a preferred methodof shifting the platen is shown, and will now be described. The rail 42 is supported at its ends on standards 50. 4 and S.) These standards oscillate on pivots 5l. In order to maintain the top of the platen as much as possible in the same horizontal plane, so that the type may always strike it squarely with the same force, it is important.

that the pivots 5l be placed as low as possible. The frame 2S, which completely surrounds the machine, is supported on legs 52, and thelugs 53, hanging from the frame and carrying the pivots 5l, extend nearly to the level of the bottom of said legs. It is desirable thatthe majority of impressions shall be given to the platen when it is vertically over the pivots 5l,

ful characters as j, f), or any.

others which may be found convenient for special use.

The use of two keys additional to the twenty-six necessary for the alphabet enables the comma and hyphen to be'mounted in the same part of the type-block as the lower-case.

letters, thus avoiding the most frequent cause for employing the shifting-key. The keys are so arranged on the board as to bring those most used in the center and those most often associated into such relation as to be conveniently operated. The types are also arranged. in one or the other group on opposite sides of the platen, according to the frequency of their use, the intention being to have one group used as much as the other. The type-blocks are made removable from their carriers, so that they can readily be replaced by others which may be newer or of a different font. 'lhe end types l of each typeblock 2 are preferably arranged at opposite inclinations to the intermediate type to make up for the slight difference in angle of the platen when'it is oscillated under-the same. The result of this inclination is that each type will strike the platen fairly on its face. Strictly the faces of the three types on each block should lie in a circle struck from the pivots 97 of the paper-carriage; but in order to avoid possible striking of one type Aof the block accidentally when another type of the same block is brought against the platen the types are made to` project sub- (See especially Figs.

stantially equal distances downward from the type-block, they printing-faces of the endy type being, however, at suitable inclination to that of the central type. The platen is held normally with its supports vertically over their pivots. It is returned automatically to that position by a centering-spring 54, which is wound on a lug or drum 55, fixed to one of the standards 50. The two ends of the spring pass forward on opposite sides of two lugs 56 57, the first fixed to frame 28 and the other to a lever 58, which extends: forward to the key-board, where it has a key or finger-piece 59. Depression of key 59y will thus tilt the plateny forward against the action Of one end of spring 54, while elevation of the same .key above its normal position will tilt back the platen against the action of the other end of spring ef, and the release of the key'will in either case bring the platen and its supports back to the upright medial position. A button 60, Fig. 2, pivoted to the frame 28 may be swung, with its lug 60, under or over the key 59 to hold it in elevated or depressed position as long as desired; but any desired device may be substituted for accompli'shing the purpose of this button.

Besides the oscillatory movement with its supports just described', the platen has two other movements--one a step-by-step movement transverse of the machine on the balls 43 to properly space the characters and words of a line, the other a rotary movement on its trunnions to shift the paper from line to line. The first of these two movements is imparted by a spring wound in customary Inanner in drum 6l, which has a cord, strap, or other means of connection 62 with the bar Lil of th'e paper-carriage. This spring exerts, as is customary in such machines, a constant pull to the left on the paper-carriage, and the latter is released by an escapement controlled by the keys. rlhis escapement will now be described.l

63 is a rack hanging loosely from pivots 6i,

carried by lugs 65 on the bar 4l of the paper-l carriage.

66 is a rock shaft or bar pivoted in inclined bearings at 67 67 on one oscillating standard 50 and rail 42, respectively. At its upper end the inclined rock shaft or bar 66 has a horizontal spring-arm 68, carrying two studs 69 69,0ne on each side of rack 63 and both preferably bearing anti-friction rollers 70 70, which closely hold the rack 63 while allowing it to run between them. A rigid projection 66L on said rock shaft or bar 66 strengthens the spring-arm 68 and renders its normal action in shifting t-he rack prompt and positive, while not interfering with the forward movement of the rack against the action of the spring-armS when it is desired to disen'gage the said. rack from both of its pawls 83 8S.

71 is the spacer-bar or yoke, having lugs 72 pivoted on cross-bar or girder 34E along with the key-levers. It is of U form and crosses the machine immediately under all of the type-moving key-levers. and sufficiently forward its pivots to afford an efficient leverage.

In addition to the key-levers 24, connected with the type-carriers, a lever 73 is employed, also pivoted on cross -bar 34: and overhanging the spacer-bar or yoke 7l. This lever is preferably arranged in the middle of the series of levers, so that its key 74 may be placed in front of the middle of the key-board, so asto be capable of operation readily by either hand.

To shorten the machine for transporta-tion, the key 74 is preferably hinged toits lever 73 and has a square-ended pintle 7 5, adapted to be engaged by spring 76, and so hold the key in extended or folded position.

rlhe spacer-bar 7l has a rearwtardprojecting arm 77, Fig. 8, on which is a lip 78- i-n front of an arm 79 of rock shaft or bar`66. A spring 80, fixed at on'e'end 8l to oscillating standard 50 of the paper-carriage, has its other end fixed to arm 79 of rock shaft or bar 66. This spring presses constantly forward the outer ends of arms 68and 79 of the rock shaft or bar 66. and thereby keeps the rack 63 normally tilted forward and the spacerbar 7l normally up close under the key-le vers, While depression of the spacing-key 7i or any of the keys 1l will force down the spa cer-bar against the action of spring 8O and, rocking the shaft or bar 66, shift or tilt the rack 63 to the rear. Normally the rack, being tilted or inclined forward, has its teeth engaged by those of segmental pawl 83,which is pivoted at 84- on a screw or pin iixedto the rail 42. The pawl 83 is arrested by its plate 85, impacting on a sound-deadening pad or stop 86, preferably of cork, carried by a chambered lng S7 on rail 42. Then moved to the rear by the depression of a key, the rack leaves the teeth of pawl 823 and engages those of a pawl 8S, fixed to the rail 42, im-

mediately in rear of movable pawl 83, and with its teeth in register with those of the latter. The pawl 83, freed from the rack, is1

forced to the right past one or two or more teeth of the rack byaspring S9 until arrested by a stop 90 at such a point that its teeth will be again 'in register with those of the rack. The stop 90 is preferably of av sounddeadening material, such as cork, "mounted in a chambered lu'g 9i, fixed to the pawl 88 or directly to the rail42. The pawl 83 is now ready to again receive the rack 63 as it` asshown, lasting a long time without necessity for adjustment. moved step by step to the left by the mechanism just described until a line is about The paper-carriage is IIO completed, when the hammer of a gong 92 is operated by a projection 93 from the pendent arm 49. Y

For moving the carriage back again to the right in order to commence a new line ot' writing, the handle or thumb-piece 94 is used. This thumb-piece has a rounded bowl to receive the thumb and arms 95, turned up on the sides thereof. It is hung from the righthand trunnion of platen 12 by these arms. The rack 63 has an arm 96, projecting to the right and then upward under thumb-piece 94. When, therefore, the thumb is placed on thumb-piece 94 and the latter is slightly depressed, the arm 96 will be pressed to the rear and the rack 63 forward, freeing the rack from both of the pawls 83 88 and allowing the paper-carriage to be moved freely to right or left by pressure applied sidewise to thumbpiece 94. A round-toothed wheel 97 is keyed to the trunnion 39 between the arms 95 of the thumb-piece 94. A pawl 98, pivoted to the arms 95, bears on the toothed wheel 97. By placing the forefinger under piece 94 and raising it the wheel 97 is turned and the platen rotated to feed forwardthe paper from line to line for any desired distance. The wheel 97 has a neck 99, Fig. 7, through which is passed the key 100, which fixes it to the trunnion 39. Upon this neck and between the wheel 97 and one of the arms 95 of the thumb-piece is coiled a spring 101, whose projecting ends pass on both sides of the flattened horizontal portion of pawl 98 and so hold it against the wheel 97. A pin 102, Fig. 5, projecting from any portion of the frame of the paper-carriage, has its end lying between the free ends of spring 101, so thatone or the other-end of the spring will always abut against said pin when the thumb-piece is raised or depressed, thus returning the thumbpiece to its normal central position. Another pin or stud 103 on the horizontal arm 104 of the paper-carriage frame arrests the upward motion of the thumb-piece always at a fixed point- It will thereupon be observed that the amount of rotation of the platen with each upward movementof the thumb-piece may be adjusted by causing the pawl 98 to engage with the toothed wheel 97 sooner 0r later in its upward movement. To this end a iiat cam 105 is pi fated on the trunnion 39, close to wheel 97. It projects slightly beyond the periphery of wheel97 and lifts the pawl 98 from the teeth thereof for-such portion of the movement of the thumb-piece as may be desired. The cam has a spring-metal finger-piece 10G, carrying a pin 1977 adapted to enter any one of a series of holes in a segment 108, fixed to the carriage-frame. While the pawl 98 will engage with the rounded teeth of wheel 97, so as to turn the platen when the thumbpiece 94 is raised, it will not when thethumbpiece is in normal position obstruct movement of the wheelin either direction. A handwheel 109 on the trunnion 89 on the left of the platen may therefore be used for rotating the platen at will when,either for inserting the paper or to shift it back or forth', the regularly intermittent movement afforded by the thumb-piece 94 is not desirable; or the toothed Wheel may be used as a hand-wheel.

The paper-holder is most clearly shown in Figs. 3 and 4. 1t consists, mainly, of two bent spring-wire cages 110 111, tixed, respectively, to the front and rear of the paper-carriage. The cage 110 is hung on the bottom of a guide-plate 112, whose upper edge is lixed to the bar 41. This plate extends from side to side of the carriage, and serves to effectually direct the paper to its curved or rolled position in the cage. The upper part of the cage 110 has downward extensions 113 and upwardly-extending arms 114, to which is hinged a graduated pressure-bar 115. Links or arms 116 are iixed to the ends of pressure-bar 115, and pivoted at 117 on horizontal arms 104 of the paper-carriage, said bar being given a pressure toward the platen by the contractile tension of the spring-wire cage. Then the pressure-bar is raised to open the cage, the links or arms pass over or just beyond their center, and the line of pressure or tension being now immediately over or a little in front of the pivoted point the bar is held open by the spring action of the cage. The cage 111 at the rear of the platen is hung from bar 41 of the paper-carriage. It has downwardly-extending` arms 113, similar to those on cage 110, and, like the latter, so disposed as to leave room for the paper to enter.

. 121 is a rear paper-holding roller havingits end pivots held by links 120, pivoted on arms 104. (See Fig. 12.) From the pivots of thc roller 120 a bar 1.19 (immediately in rear of the platen) is pendent by arms 122. From this bar the cage 111 hangs by loops v118.

The spring-pressure of the cage is constantlydownward, and it thus holds the roller 121 against the platen. The paper may be i11- serted on raising the bar 115 till the links 110 stand immediately over or just beyond their center. The springwires of the cage will now hold the cage open, the downward pressure on links 116 being over or in front of their pivots 117. Sulicient space is thus provided between the bar 115 and the platen to enable the paper to enter, and it is accordingly slipped into this space, the side to be written on being toward the operator. The guide 112 causes the paper to roll itself into position in the cage. The top of the paper is laid over the platen, face up, its edge inserted under roller 121, and the bar 115 snapped down to hold it on the platen. The paper may now be written on, shifted, and removed by means which have already been fully described.
